ALBERT LANGSTROM, OF COUNCIL BLUFFS, IOWVA, ASSIGNOR OF ONE-HALF TO A.B. WVALKER, OF SAME PLACE.

TRANSOM-LIFTER.

SPECIFICATION forming part of Letters Patent No. 377,312, dated January31, 1888.

Application filed June 15, 1887. Serial No. 241,407. (No model.)

To all whom it may concern:

Be it known that I, ALBERT LANGSTROM, a citizen of the United States,residing in Council Bluffs, in the county of Pottawattamie and State ofIowa, have invented certain new and useful Improvements inTransom-Lifters, of which the following is a specification.

The object of this invention is to provide means for convenientlyoperatingi. 6., opening and closinga transom-window and looking it in anopen, partially open, or closed po sition.

To this end it consists in the mechanical arrangement hereinafter fullydescribed, and illustrated in the accompanying drawings, forming a partof this specification, and in which- Figure 1 is a side elevationshowing the transom-window closed and locked. Fig. 2 is a perspectiveview showing a modification of the device shown in Fig. 1, and Figs. 3and 4 are views in detail. v

In the drawings, 1 represents the frame of the door to which thetransom-window 2 is hinged. Attached to one of the stiles of thetransom-window is a metal bracket, 6, which is bent outward at its freeend and terminates in a coarse screw, 5. The upper end of thetransom-lifting rod 3 has an eye, 4., which is adapted to screw on suchlateral threaded projection of the bracket 6. This means of connectionenables the two parts (3 and 6) to be very easily and quickly attachedand detached. The lower end of the rod 3 is provided with afinger-piece, 10, as shown in the drawings. This rod 3, which isslightly bent to give it a spring, is supported and adapted to slide inbrackets 11 and 12, that are attached by screws or otherwise to the jambof the doorframe. The lower one of these brackets, 12, has a hole,through which the rod 3 slides, made somewhat larger than the rod andstraight across the side next the window-frame to form a tongue, 13,which engages with one of a series of transverse slots, 14, cut in theunder side of the rod, and serves to lock the rod and thereby thetransom-window at any position in which it may be placed.

It will be understood that the notches 14 in the lifting-rod are to bearranged so that the lifter will automatically lock itself when lowered,and thus prevent the window being opened from the outside.

To insure the transom-window being securely held, the liftingrod 3should have sufficient spring to force any of the notches 14 upon thetongue 13 on the lower bracket when one is brought opposite the same.The rod 3 is provided with additional security by means of alocking-finger, a, pivoted to the lower bracket, 12. This finger a, whenone of the notches in the rod 3 is in engagement with the tongue on thelower bracket, hooks over the said rod, and thus locks it in thatposition.

The perforation in the lower bracket being 6 enlarged, allows thenecessary play of the rod for disengagement with the tongue 13 when thetransom-window is to be opened or closed. The upper end of thelifting-rod should be bent outwardly a little to obviate severe bind- 7oing in the upper bracket, and thus prevent the lifting-rod being worn ormarred.

The foregoing arrangement is equally well adapted for lighttransom-windows hung as shown in the drawings or heavy transom-win- 7dows hung in the center.

For heavy transom-windows hung from the upper edge, I modify the deviceshown in Fig.

1 of the drawings by the addition of an arm, 15. This arm 15 isconnected at its lower end by a wire loop-hinge, 16, to the rod 3, theupper end being connected with the transomwindow, as shown by thedrawingsi. e., like the connection therewith of the upper end of thelifting-rod when arranged for light transom-windows, as shown in Fig. 1.

\Vhen the lifting-rod 3 is arranged for heavy transom -windows, itsupper end is passed through a bracket, 17, Fig. 2, designed to hold therod straight, and thus through the arm 15 facilitate the adjustment ofthe transom-window.

From the foregoing it will be seen that I have provided a simple andeasy means for operating transom-windows in houses, cars, 5 or otherplaces where they are located beyond the reach of the hands, and theconstruction ward, as specified, and a series of fixed brackbeing suchthata child can Work it with the ets, with one of which the spring ofsaid rod 10 ease of agrown person. causes it to engage, as shown anddescribed.

Having thus described my invention whatI 5 claim as new, and desire tosecure by Letters ALBERT LANGSTROM' Patent, is Witnesses:
